Php mail()打破了650个字符长的Url

我使用 PHP邮件功能发送链接与许多参数.编码后的url长度可以是650或更多字符,因为它保存变量以重新填充表单.

当我点击我的电子邮件中的链接时,它已损坏,因为在URL中的某处插入了一个空格.

继承我的sendMail功能：

protected function sendEmail($to,$subject,$body) {
        $headers  = 'MIME-Version: 1.0' . "rn";
        $headers .= 'Content-type: text/html; charset=iso-8859-1' . 'rn';
        $headers .= 'From: Sales Order From <sales@imninjas.com>' . 'rn';
        $headers .= 'X-Mailer: PHP/' . phpversion() . 'rn';

        $body = '<html><body style="font-size: 10pt; font-family: Arial,Helvetica,sans-serif;">'.$body.'</body></html>';

        return mail($to,$body,$headers);
    }

下面是我用sendMail调用的代码.其’$salesUrl = $this-> getSalesFormUrl();’这是650个字符的网址塞满了编码的参数.

function emailRep() {
        $params = $this->getParamaterArray();
        $shortUrl = $this->getShortUrl();
        $salesUrl = $this->getSalesFormUrl();

        $mailSubject = "Return to the sales order form for ".$params['clientName']." at ".$params['company'].".";

        $mailBody = "The following information is from an order created on,".date("l,F j,Y at g:i a").",<br/><br/>";
        $mailBody .= "Customer Contact Information:<br/>";
        $mailBody .= "Name: ".$params['clientName'] params['company']."<br/>";
        $mailBody .= "Shortened Url to Send to the Customer:<br/>";
        $mailBody .= ($shortUrl) ? "<a href='".$shortUrl."'>".$shortUrl."</a><br/><br/>" : "There was an error shortening your url.<br/><br/>";
        $mailBody .= "The URL back to the sales form: For sales rep use only,<strong>Do not give to the customer</strong>.:<br/>";
        $mailBody .= "<span style='font-style: italic;'>Some email clients add special characters to long urls. If the link does not work then copy and paste it into your browser.</span><br/>";
        $mailBody .= "<a href='".$salesUrl."'>".$salesUrl."</a><br/><br/>";

        return ($this->sendEmail($params['repEmail'],$mailSubject,$mailBody));
    }

这是我在电子邮件中收到的URL,您会注意到URL中间的空格’… BhsNKq Jsd_x4 …’.即使我发送完全相同的网址,每次都会在不同的地方发生这种情况.为了证明这一点,我在emailRep方法中没有空格的情况下对此网址进行了硬编码并多次发送.空间四处移动.

这是我用来在通过电子邮件发送之前对url参数进行编码/解码的代码.

class UrlEncoder {
    function compressUrl($url) {
        return rtrim(strtr(base64_encode(gzdeflate($url,9)),'+/','-_'),'=');
    }

    function uncompressUrl($url) {
        $startParams = strrpos($url,"?");

        if($startParams) {
            $paramaterString = substr($url,$startParams);
            $host = substr($url,strrpos($url,"?"));
            $uncompressedParamaters = gzinflate(base64_decode(strtr($paramaterString,'-_','+/')));
            return $host."?".$uncompressedParamaters;
        } else {
            return NULL;
        }
    }
}

我该如何防止这个空间？我知道我可以用bit.ly这样的东西缩短URL,但它是一个内部工具.我觉得必须有办法阻止插入空间.

谁在正确的思想中使用650个字符长的查询字符串？

我的建议是保存查询字符串服务器端.将它放在带有AUTO_INCREMENT字段的数据库中,然后就可以获得它的ID.然后,您只需将URL发送为http://example.com/?email_key=ID_GOES_HERE,这是一个更短的网址.然后只需从数据库中查找查询字符串.

完成.
